From April 26 to May 2, New York's getting an obscure holiday -- Rioja Restaurant Week. It's like Normal Restaurant Week, but instead of being inspired merely by New Yorkers' inherent desire to eat fine foods on the cheap, it throws oenophilia into the mix. La Rioja, an autonomous region in northern Spain, produces a full range of wines ... rosés, reds, whites. Riojans claim their wine pairs better than any other in the world, and to prove it, they've set up a bunch of deals with a few participating restaurants all over Manhattan to get the word out.

For example:

● A 25% discounted bottle of Rioja at Stanton Social, Veritas, and The Mermaid Inn.

● A $50 prix-fixe at Chinatown Brasserie, Tailor, and Flex Mussels.

● Call for changing Rioja specials at Lure (where you can also use your BlackBook iPhone app to get a sweet happy hour deal), Smith's, Las Ramblas.
